Find the volume of a pyramid with a square base, where the perimeter of the base is 10.7\text{ ft}10.7 ft and the height of the

Airida [17]

Answer:

$V=23.37\ ft^3$

Step-by-step explanation:

Given that,

The perimeter of the base of pyramid, P = 10.7 ft

The height of the pyramid, h = 9.8 ft

We need to find the volume of the pyramid.

The perimeter of square is given by :

4s = 10.7, s is side

s = 2.675 ft

Now the volume of pyramid is given by :

$V=\dfrac{lbh}{3}\\\\=\dfrac{2.675^2\times 9.8}{3}\\\\V=23.37\ ft^3$

So, the volume of the pyramid is equal to $23.37\ ft^3$ .

What is the minimum force required to prevent a ball weighing 22.6 lb from rolling down a ramp which is inclined at 39.0 degrees

Alona [7]

The correct answer is 14.2 lb which is choice D.

Let:

F = minimum force required to prevent ball from rolling down the ramp

The formula will be:

F = w * sin theta

F = w * sin (39 degrees)

F = 22.6 * sin (39)
= 14.2 lb (this is rounded to the nearest tenth)
